Ember - sort array by multiple properties in multiple directions

Question

I need to sort a collection of Ember Models by multiple properties, and not necessary in the same direction/order. I.e. I need to sort by property a in ascending order and by property b in descending. Is there a way to achieve this?

Update

I tried setting the sortAscending property to a array, but it is not working. After looking into the source it seems that this functionality is not supported out of the box(yet).

Answer 1

In your ArrayController:

sortProperties: ["propA:asc", "propB:desc"]
sortedModel: Ember.computed.sort("model", "sortProperties");

Then reference sortedModel in your template's #each handler.
